Application filed September 23, 1919. Serial No. 325,690.

To all whom it may concern."

Be it known that BUSI-IROD C. WASHING- TON and STUART K. Joion, citizens of the United States, residing at Washington, in the District of Columbia. haveinvented certain new and useful Improvements in Fans, of which the following is a specification, reference being had therein to the accompanying drawing. 1 l ,p

The invention relates to fans and has for itsobject to provide a hand operated rotary fan and to provide av reciprocating double rack operating gears in mesh with gears which operate the fan shaft and ratchet and.

ing the rotation of the fan.

A further object is to provide spring means whereby the reciprocating double rack on its outward stroke will be assisted .in its movement, thereby relieving the strain on the finger of theoperator during the reciprocation of the'double =rack.

A further object is to provide a rotary fan particularly adapted for dances, usein. mov ing picture theaters and the like; said rotary fan being hand operated and; reduced to its minimumin size so that the same may be easily carried in a purse, pocket or if so desired suspended from ,a' chain from the wrist. Also to so construct the driving mechanism for the rotary fan so that it will be double-acting, that is operate the same through gears and racks in such a manner that as the racks are reciprocated the fan will be rotated on both strokes of said racks.

Withthe above andother objects in View the invention resides in the combination and parts as hereinafter set claimed, it being understood that changes in the pr cise mbodiment of the invention mechanism.

may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a view showing the position in which'the fan is preferably held for operation.

Figure 2 is a rear view of the fan.

Figure 3 is a plan view of the fan with parts broken away to illustrate the driving mechanism.

Figure 4-. is a rear view of the fan with parts broken away to show the driving Figure 5 is a sectional view taken on line 5-5 of Figure 2.

Figure 6 isa detail view of the under sides of the driving gears and ratchets and dogs through the medium of which the driving gears are revolved alternately upon the reciprocation of the racks.

Figure 7 is a sectional view takenon line 7'-7'of Figure 3.

Referring to the drawings, the numeral 1 designatesa base plate upon which the fan operating mechanism is carried and is adaptedto be supported. Base plate 1 has at one side thereof a finger engaging member 2,

in which member the finger oflthe operator is adapted to enter. however it is to be understood that this member may be of any depth and wide enough to receive one or more fingers, so as to stabilize the fan as a whole during a fanning operation. How

ever for purpose of illustration, curved lugs 3 are shown extending outwardly and in- .wardly from the sides of the member 2 and between said lugs and the body of. the fan, the fingers'are adapted to pass while one or 1ignore fingers are disposed within the mem- A double reciprocating rank 4: is slidably mounted on one face of the plate 1 and is held in position by a guide plate 5 which is disposed on a spacing block 6 and through which guide plate spacing block and through plate 1, screws 7 pass. Spacing block 6 is disposed within the elongated aperture 8 in the reciprocating double rack. Thus it will be seen that as the double rack bar 4 is reciprocated that the racks 9 and 10 will be guided in their movement and the double rack bar 4: as a whole prevented from displacement. Guide plate 5 has rotatably mounted in a bearing 11 thereof a fan shaft 12, Which fan shaft has pivotally secured to the outer end thereof a series of faniblades 13 which may be of any construction but are preferably foldable and of a type wherein as the fan shaft 12 is rotated the blades will automatically open. Fan shaft 12 also has abeaiin 14 in a bridge plate 15, whieh bridge plate is supported on posts 16 carried by the body plate 1 thereby holding the fan shaftin position. Keyed or otherwise secured to the fan shaft 12 isa gear 17, which gear is adapted to be rotated in the same direction by means, of gears 18, which mesh with the gear 17 and are disposed on opposite sidesof the same. Gears 18 are loosely mounted on shafts 19, supported in bearings 20 and 21 in the bridge plate 15 1 and the base platel. The upper faces of 37 is disposed. dlsh shaped receptacle 36 a inirror .38 is sethe gears 18 are provided with annular depressions 22 in which depressions spacing washers 23 are disposed, said spacing washers having a tight fit on the shafts 19 are provided to prevent the frictional bind: ing of the upper faces ofthe gears 18 against the under face of the bridgeplate 15. Gears 18 are held in position by pinions 24 which are loosely Inountedon the shafts 19, the upperends of said pinions being provided with integral ratchets 25 means of which ratchets and spring actuated pawls 26, gears 18 and pinions 24 will be locked to rotate with each other alternately with the reciprocation of the racks 9 and 10 which are carried by the reciprocating rack bar 4. Secured as at 28 to the end of the rack bar 4 and to the base plate as at 29 is a coil spring 30, which coil spring. is adapted to assist the return of the rack bar 4 to its outward position, however it is to be understood that this spring if so desired be eliminated and the rack bar 4 moved to its outward position by means of the finger of the operator, preferably the thumb which is disposed within the socket 31 atthe outer end of the rack bar.

A casing 32 is provided which casing is adapted to enclose the mechanism of the fan. Casing 32 is preferably formed in two sect1on's,:33 and 34 telescopically engaging each other and are provided with diametrically arranged and registering apertures 35 for the reception of the shank of the member 2 and the reciprocating rack bar 4Q The rear portion of the casing 32 has deta'chably in which dish shaped receptacle 'apowder In the, bottom of the secured thereto a dish shaped receptacle 36,

cured in any suitable manner; It will be seen that when it is desired to u'se a powder 'pufi and mirror it will only. be necessary to "remove the dish shaped member 36 from the rea of tliec'asing 2 v I g and that said dish shaped 'lliber, ma

be quickly removed and replaced. Dish shaped- 3G may be threaded or frictionally held on the casing 32.. a -5 Dogs 26 are pivoted on the gears 18 as at 39 and are normally held in engagement with theteeth of the ratchet 25 by means of springs 40, which springs may be secured to the gears 18 in any suitable manner but preferably soldered as at 41.

It will'be s'eenby referring to Figures 4 and 5 that as the rack bar 4 is forced in: wardly that the rack 1Ov will cause the pinion 24 torevolve in the direction of the arrow a, which willcause the dog. '26 onthe gear 18 to engage in the teeth .of the ratchet 25, thereby locking the gear 18 a1n'd pinion together, and 'asthegear 18 meshes the 19 independently. When the rack ba114'returns to its outward position it will be seen that its engaging pinion Will go infthe opposite c'lirect'ioi'i thereby throwing its ratchet into engagement with the nose of the, dog 26* so that the ge ar 18 will, be caused to rotate. the direction of the-arrow 0 thereby continuing the rotation of the fan shaft 12 iii th'ed'irection ef the arrow From the above it will be seen that a hand operated fan is provided wherein a' continuboth strokes of the reciprocating rack bar, and one whereina full stroke i's not necessary as the reciprocation may be stopped at any point or may be of any length. It will also be seen that by means of the finger engaging Inenr'ibers the possibility of the operators fingers extending through to such a point where th'eywill' be engaged by the rotating fan blades is obviated."
